Does Macquarie Infrastructure Corporation (NYSE:MIC) Have A Volatile Share Price?

Simply Wall St

If you're interested in Macquarie Infrastructure Corporation (NYSE:MIC), then you might want to consider its beta (a measure of share price volatility) in order to understand how the stock could impact your portfolio. Modern finance theory considers volatility to be a measure of risk, and there are two main types of price volatility. The first type is company specific volatility. Investors use diversification across uncorrelated stocks to reduce this kind of price volatility across the portfolio. The second sort is caused by the natural volatility of markets, overall. For example, certain macroeconomic events will impact (virtually) all stocks on the market.

Some stocks see their prices move in concert with the market. Others tend towards stronger, gentler or unrelated price movements. Beta can be a useful tool to understand how much a stock is influenced by market risk (volatility). However, Warren Buffett said 'volatility is far from synonymous with risk' in his 2014 letter to investors. So, while useful, beta is not the only metric to consider. To use beta as an investor, you must first understand that the overall market has a beta of one. A stock with a beta below one is either less volatile than the market, or more volatile but not corellated with the overall market. In comparison a stock with a beta of over one tends to be move in a similar direction to the market in the long term, but with greater changes in price.

NYSE:MIC Income Statement, October 28th 2019

How does MIC's size impact its beta?

Macquarie Infrastructure is a reasonably big company, with a market capitalisation of US$3.4b. Most companies this size are actively traded with decent volumes of shares changing hands each day. It takes deep pocketed investors to influence the share price of a large company, so it's a little unusual to see companies this size with high beta values. It may be that that this company is more heavily impacted by broader economic factors than most.

What this means for you:

Beta only tells us that the Macquarie Infrastructure share price is sensitive to broader market movements. This could indicate that it is a high growth company, or is heavily influenced by sentiment because it is speculative. Alternatively, it could have operating leverage in its business model. Ultimately, beta is an interesting metric, but there's plenty more to learn.
